Tubes for Cal Audio Labs Alpha Processor

I have a Cal Audio Labs Alpha tube analog processor. Was told certain tubes fail quickly in this unit. Any recommendations? Thank you Dan

Tube selection has always been made based on ancillary equipment and speakers. I like a clear neutral tone, one that if it errs at all errs on the warm side. I'm presently using EI12AX7E (grey plates/steel pins).
